Pittsburgh Public Schools officials have enacted a policy that sets 50 percent as the minimum score a student can receive for assignments, tests and other work. District spokeswoman Ebony Pugh said, the 50 percent minimum gives children a chance to catch up and a reason to keep trying. If a student gets a 20 percent in a class for the first marking period, he or she would need a 100 percent during the second marking period just to squeak through the semester. The district and teachers union issued a joint memo to ensure staff members' compliance with the policy, which was already on the books but enforced only at some schools. At this rate, it won't be long before schools institute double extra credit Mondays and Fridays to ensure students don't take three day weekends.

CWmike writes "Every June and November a new list of the world's fastest supercomputers is revealed. The latest Top 500 list marked the scaling of computing's Mount Everest — the petaflops barrier. IBM's 'Roadrunner' topped the list, burning up the bytes at 1.026 petaflops. A computer to die for if you are a supercomputer user for whom no machine ever seems fast enough? Maybe not, says Richard Loft, director of supercomputing research at the National Center for Atmospheric Research in Boulder, Colo. The Top 500 list is only useful in telling you the absolute upper bound of the capabilities of the computers ... It's not useful in terms of telling you their utility in real scientific calculations. The problem with the rankings: a decades-old benchmark called Linpack, which is Fortran code that measures the speed of processors on floating-point math operations. One possible fix: Invoking specialization. Loft says of petaflops, peak performance, benchmark results, positions on a list — 'it's a little shell game that everybody plays. ... All we care about is the number of years of climate we can simulate in one day of wall-clock computer time. That tells you what kinds of experiments you can do.' State-of-the-art systems today can simulate about five years per day of computer time, he says, but some climatologists yearn to simulate 100 years in a day."

By clicking yes you are failing the Windows Darwin Test.' Nearly half of them said all they cared about was getting rid of these dialogs."

Kristina from Science News writes "Combining computer simulations with data about the way starlight shines through Saturn's rings suggests the individual grains are big and thus could have been around a good 4 billion years, not the mere 10 million to 100 million previously suspected. What may have thrown earlier observations off is the chance that the grains aren't evenly distributed, but clump here and spread out there."

phantomflanflinger writes "As you may have heard already, Microsoft have announced their intentions to buy back $40 billion in stock from their investors, in the biggest single buy-back plan in business history. The announcement has given Microsoft shares a small gain but they still stand significantly below their level in January — before Microsoft's unsolicited bid for Yahoo!. The announcement of the plan has also created new speculation about a now-or-never deal with Yahoo!."

Amber G5 writes "SecureWorks published the locations of the computers from which the greatest number of cyber attacks were attempted against its clients in 2008. The United States topped the list with 20.6 million attempted attacks originating from computers within the country, and China ran second with 7.7 million attempted attacks emanating from computers within its borders. This was followed by Brazil with over 166,987 attempted attacks, South Korea with 162,289, Poland with 153,205, Japan with 142,346, Russia with 130,572, Taiwan with 124,997, Germany with 110,493, and Canada with 107,483."

CrazedSanity writes "I have been working at my state job for about 7 months now, using the Exchange plugin for Evolution to check my email. Very recently the higher-ups decided to migrate to Exchange 2007, which effectively destroyed my ability to check my email through any method other than webmail (which means I have to constantly refresh/reload the webmail window). I'm sure somebody else has encountered the problem, but I'm wondering if anybody has come up with a working solution?" Note: CrazedSanity's looking for a client that will work with Exchange in a situation where replacing the Exchange install with an open-source equivalent isn't an option.
